| Title | Failure to Maintain B.5.b Mitigating Strategies |
| Description | An NRC-identified finding of very low safety significance (Green) and NCV of Title 10 of the Code of Federal Regulations (10 CFR) 50.54(hh)(2), Conditions of Licenses, the Unit 2 FOL Condition 2.N, and the Unit 3 FOL Condition 2.AC was identified for failure to maintain strategies for addressing large fires and explosions. Specifically, Entergy failed to maintain the B.5.b strategies when the sites diesel contingency pump (B.5.b pump), B5B-101-PMP, was declared non-functional and unavailable on March 20, 2017, due to a deficiency associated with the pumps engine and failed to promptly restore the pump to a functional status or establish any 3 compensatory measures. Entergy entered this issue into its CAP and promptly completed repairs to the B.5.b pump. This finding was more than minor because it is associated with the Protection Against External Factors (e.g., fire) attribute of t he Mitigating Systems cornerstone and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent core damage. The team evaluated the significance of the finding in accordance with IMC 0609, Appendix L, B.5.b Significance Determination Process. The finding was determined to be of very low safety significance (Green) because although the B.5.b pump was considered unavailable, the team concluded that the pump was recoverable. This finding had a cross-cutting aspect of Resources, in the area of Human Performance, because leaders did not ensure that personnel, equipment, procedures, and other resources were available and adequate to support nuclear safety. Specifically, procedural guidance and equipment were not available to operators to implement adequate compensatory measures when the B.5.b pump became non-functional and unavailable. [H.1] |
